Abstract

Based on nanoindentation tests and analysis, the constitutive relationship of the Interfacial Transition Zones (ITZs) in Recycled Aggregate Concrete (RAC) is put forward. Together with the meso/micro-scale mechanical properties of each phase in Modeled Recycled Aggregate Concrete (MRAC), the plastic-damage constitutive models are employed in numerical studies on MRAC under uniaxial compression and uniaxial tension loadings to predict the overall mechanical behavior, particularly the stress-strain relationship. After the calibration and validation with the experimental results, a parametric study has been undertaken to analyze the effects of ITZs and new mortar matrix on the stress-strain relationship of MRAC. It is revealed that the mechanical properties of new mortar matrix and relative mechanical properties between ITZs and mortar matrices play a significant role in the overall stress-strain relationship and failure patterns of MRAC under both uniaxial compression and uniaxial tension loadings.
